As of right now, you can play previously exclusive games like Uncharted 3 and Shadow of the Colossus on a Windows laptop. I know, because I did.

The catch: you'll be playing those games over the internet with Sony's streaming game service, PlayStation Now. Think Netflix.

PlayStation Now has already been around for a couple of years on the PS4, PS3, PS Vita handheld, plus a handful of Blu-ray players and smart TVs. For $20 a month or $45 for three (£13 monthly in the UK, but alas, not available in Australia), the service gives players unlimited access to a long list of over 400 PlayStation 3 games. (The service is available only in those countries as well as in Canada and Japan, with Belgium and the Netherlands currently in beta.)

The $24.99 PlayStation USB Wireless Adapter will let you connect a controller wirelessly.

What changes is the size of Sony's audience. With a Windows laptop or tablet, you aren't tethered to a big-screen TV. You could theoretically take these PlayStation games anywhere -- and wherever you go, your saved games stream with you. (Sony says that PS3 players can transfer their saves to PlayStation Now via PS+ Cloud Storage. You can access it by pressing the PS Button and going into the PS Now XMB.)

There are some caveats, though. In addition to the pricey monthly subscription and the stable internet connection, Sony recommends your Windows device have a 3.5GHz (or faster!) processor for best results.

(That's strange, because streaming game services usually don't need a lot of local processing power -- years ago, I streamed Mass Effect 2 to an old netbook with no real trouble -- but Sony offers a seven-day free trial so you can test it out.)

And you'll need a DualShock 4 controller to play on Windows, instead of the older DualShock 3 that worked just fine with PlayStation Now on other platforms.

Still, the newer controller comes with perks: you'll be able to plug it in with any standard Micro-USB phone charger cable, or a new $25 wireless USB dongle that Sony will ship this September. That dongle will work with PS4 Remote Play (the software that lets you stream your own PS4 games to PC) as well.

Eric Lempel, head of Sony's PlayStation Network, wouldn't talk about future plans for PlayStation Now in an interview. He couldn't say whether the service might come to smartphones, for instance, or whether Sony might stream newer PS4 titles or older PS2 titles later down the road.

It's not hard to see a future where you might not need a physical PlayStation at all -- much like how you may not need an Xbox -- but Lempel didn't talk about that.

Today, it's just about bringing this small chunk of PlayStation to a new audience. "The PlayStation launched so many great franchises, and this brings new life to them," said Lempel.
